                    The IPv6 Segment Endpoint Option
                    draft-bonica-6man-seg-end-opt-03

Abstract

   This document defines the IPv6 Segment Endpoint Option.  Source nodes
   can use this option to convey internet-layer information to selected
   segment endpoints along a packet's delivery path.

1.  Introduction

   IPv6 [RFC8200] options convey optional internet-layer information to
   selected nodes along a packets delivery path.  IPv6 options can be
   encoded as follows:

   o  In a Hop-by-hop Options header.

   o  In a Destination Options header that precedes a Routing header.

   o  In a Destination Options header that precedes an upper-layer
      header.

   If an option is encoded in a Hop-by-hop Options header, it conveys
   information to every node along the packet's delivery path, including
   the destination node.  (See NOTE 1).  If an option is encoded in a
   Destination Options header that precedes a Routing header, it conveys
   information to every segment endpoint along the packet's delivery
   path, including the destination node.  If an option is encoded in a
   Destination Options header that precedes an upper-layer header, it
   conveys information to the destination node only.  (See Section 4.3.4
   of [RFC8200] )
